Problems solved by technology

[0004] In the system without flue gas bypass, the absorption tower becomes the only way for the flue gas. When all the slurry circulation pumps are out of service in an accident, the boiler must be MFT. into the absorption tower, causing greater damage to the lining of the absorption tower and tower internals

Embodiment Construction

[0020] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention, and are only examples. At the same time, it will become clearer and easier to understand by illustrating the advantages of the present invention. This system is described from two aspects of process system and operation control. The direction indicated by the arrow in the figure is the direction of gas flow.

[0021] Referring to the accompanying drawings, it can be seen that the flushing and desuperheating device at the entrance of the absorption tower in the flue gas desulfurization system of the present invention includes an emergency desuperheating water tank B, a spray layer setting C located in the flue A at the entrance of the absorption tower, connected to the accidental desuperheating water tank B The emergency desuperheating water main pipe 4 of C is set on the spray layer...

Abstract

The invention discloses an absorption column inlet flushing and desuperheating device in a smoke gas desulfurization system, which comprises an accident desuperheating tank B, a spraying installation C arranged in an inlet flue A of an absorption tower, and an accident desuperheating water header pipe 4 connected with the accident desuperheating tank B and the spraying installation C. The absorption column inlet flushing and desuperheating device in the smoke gas desulfurization system overcomes the defects that in a current soot-free bypass system, the absorption tower becomes the only way for the smoke gases to pass; and when a slurry circulating pump is completely stopped due to accident, the necessary master fuel trip (MFT) on a boiler can cause larger damage on a liner of the absorption tower and internals of the tower. The absorption column inlet flushing and desuperheating device can automatically and quickly spray and cool the high temperature smoke gases at the inlet of the absorption tower and control the temperature of the inlet of the absorption tower in an allowable scope so that the absorption tower is guaranteed from being damaged by high temperature.

Description

technical field [0001] The invention relates to a flushing and desuperheating device, in particular to a device (or system) for emergency flushing and desuperheating of the dry-wet interface at the entrance of an absorption tower. Background technique [0002] In the flue gas desulfurization device, the temperature resistance of the inner lining of the absorption tower, the demister, the spray layer and other tower internal parts is below 80°C, while the flue gas temperature at the outlet of the induced draft fan of the power plant is generally 120°C (180°C in case of failure) . When all the slurry circulating pumps of the absorption tower stop running in an accident (for example, the power of the whole plant is cut off), the flue gas will directly enter the absorption tower, which will cause great damage to the lining and internal parts of the absorption tower. [0003] In a system with flue gas bypass, when all the slurry circulation pumps are out of service due to an acc...
